FIELD: metallurgy. ^ SUBSTANCE: invention relates to powder metallurgy, particularly to self-lubricating materials for friction alloys. The material is received by sintering of powder composite containing a copper powder of 100-160 mcm size, granules of copper-plated graphite of 160-200 mcm size; at amount of 16-17 wt % with copper contents in copper-plated graphite granules of 70-75 wt %, granules of copper-plated polymer of 50-200 mcm size at amount of 7-9 wt % with copper content in granules of copper-plated polymer granules 50-60 wt %, granules of copper-plated lead of 50-160 mcm size in amount of 5-7 wt % with copper contents in granules of copper-plated lead 20-30 wt %, granules of copper-plated tin of 20-40 mcm size at amount of 3-5 wt % with copper content in granules of copper-plated tin granules 10-20 wt % and bulbar nano-structures of carbon at amount of 0.05-0.07 wt %. ^ EFFECT: receiving of material, which allows high solidity and wear resistance and provides increasing of service life of friction assemblies. ^ 2 tbl |
